I'm wondering if you're talking about the preschool where I teach. We are planning on opening up, 100% outdoors except for hand washing and bathroom. Although hand washing may be done outside - we had a staff meeting recently and our director talked about ordering hand washing supplies. At the time, I didn't think to ask her about it.
My only concern is if we're still outside in January and February - I get really cold and I am not looking forward to being outside for 3 hours every day when its 30 degrees and really humid.
